How to prepare plain paint

Car plain paint is also called solid or car solid paint. Unlike metallic car paint, the operational factors in spraying have little influence on the color change of the plain paint. In addition, the

construction conditions and construction environment have very little influence on the color of the plain paint. These factors all make plain paint easier to deploy.

But you should pay attention to the following points when deploying plain paint:

1. The "settling effect" of the masterbatch.

White masterbatches and some yellow masterbatches are the most important types of masterbatches because of the high density of their pigments, often resulting in a significant

color difference between the wet condition and the sprayed swatches. If the wet paint contains a certain amount of white paint or some yellow paint, when stirring with a paint mixing ruler

and visually comparing the standard plate, it is required that the wet paint should be prepared to be lighter and lighter than the standard plate. This is because when the wet paint is stirred,

the heavy color masterbatch does not have time to settle, and the color of the paint is lighter; while the settling occurs during the leveling time after spraying, and the light masterbatch

gathers more on the surface, and the color will be brighter. Pure, the appearance appears to be a little "dark". This is also one of the main reasons for the difference between the newly

sprayed paint surface and the dried paint surface. After drying, the paint surface will appear a little darker.

2. Try to use color masterbatch with high purity.

Cars like bright and bright colors in the choice of plain colors, mainly red, blue and yellow. Use as little black masterbatch as needed for these color blends; occasionally use a small

amount of white masterbatch to adjust brightness and vibrancy (purity), but recognize that. This will cause some degree of clouding of the color.

3. Try not to use low-strength color masterbatch as the main color

Even if you have to choose, try to use a color masterbatch with high opacity, which is most common in bright red.

4. The white will turn slightly yellow after a period of use. When blending white, try to use a low-intensity color masterbatch. It is the transparent color masterbatch. For example, the color

matching of white, because the human eye has a stronger ability to distinguish white than other colors. Therefore, the advantage of choosing a low-intensity color masterbatch is that it is

easy to control the variation range during fine-tuning.

5. The surface gloss of black plays a decisive role in judging its color difference. The newly sprayed black is easy to give people the misunderstanding that the paint surface is too dark

because the surface gloss is too high. You can wax and polish before comparing. Even adding a small amount of white masterbatch before spraying made the original black formula slightly

cloudy.

6. A small amount of white or yellow masterbatch can be added to the refinish paint when refinishing body colors that have faded from prolonged exposure.

7. Color isomerism.

Color heterogeneity is the deviation of colors reflected from different light sources (such as sunlight and lights). Looking at the more accurate model or the adjusted paint color outdoors,

when you look at the color indoors or in the spray booth, the color is out of shape. This is because the light source plays a role. Different pigments are screened and combined to simulate

the wavelength and energy of the reflected light required under the light source. Unless the exact same pigments are used, it is almost impossible for two different paints to be the same

color under different light sources.

Since the human eye can detect all wavelengths and all angles in the range of visible light, when the light source changes with the change of the surrounding environment, if there is

color heterogeneity in the adjusted color, the human eye can distinguish it.

Color isomerism is a fairly common phenomenon in color blending, and the resulting color difference is also small. If there is a serious heterogeneity phenomenon, it is basically related to

the improper selection of color masterbatch. At this time, it is no longer enough to increase or decrease the number of color masterbatches on the basis of the original formula. At this time, the color masterbatch used must be changed.
